A panda, Molly, decides to take a slide down an incline plane. She starts at the top. Her initial speed is 0 m/s. Her mass is 75 kg. The length down the hill is 250 m. There is no friction. Use equations of energy.
A. What is the magnitude and direction of the normal force.
B. What is her acceleration down the hill?
C. How long does it take for her to go down the hill?
D. What is her final velocity at the bottom of the hill?
A jet airplane is in level flight. The mass of the airplane is m = 8830 kg. What is the magnitude of the lift force acting on the plane
